Put down or leave something (7)
I believe the answer is:
deposit
I believe this is a double definition.
'put down' is the first definition.
(I've seen this before)
'leave something' is the second definition.
(I've seen this before)
(Other definitions for deposit that I've seen before include "Posited as down payment" , "Set down" , "Hoard" , "First instalment" , "Money in bank - part payment" .)
